'FlRE-HYDRANT.

SPECIFICATION forming part of Letters Patent No. 242,243, dated May 31, 1881.

Application filed February 524, 1881. (No model.)

To all whom it may concern Be it known that 1, WILLIAM L. ADAMS, of Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Fire-Hydrants; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to tire-hydrants, and it consists in the construction and arrangement of parts, as hereinafter more fully described and claimed.

In the annexed drawings, in which like parts are indicated by like letters in the several views, Figure 1 is a vertical section. Fig. 2 is a section at or a, and Fig. 3 is a section at y y.

A represents the stand-pipe, which is flan ged at the ground-level z z.

B is the top casting, secured above the standpipe to a flanged plate, D, which is arranged horizontally between them.

Within the upper part of the casting B are guides O O for the valve-rod nut G, to which is attached the end of the valve-rod H, that is operated by a screw, F, which works in the upper end of the nut G. The stem of the screw F is provided with a collar, f, that holds it in place, and a washer, f, is attached above the cap of the hydrant. The valve-rod H passes below through a stutling-box, I, which is connected by screw-threads with a nut, J, that screws into a central opening in the flanged plate D. A lock-nut, K, is placed above the plate D and around the nut J. When the nut J is screwed down its lower end rests upon the top of a pipe or tube, L, the lower end of which is screwed into the valve-seat M. The valve-rod H passes through the tube L and valve-seat M, and carries at its lower end a valve, N.

To the lower end of the stand-pipe A is secured a globe-casting, E, having an inlet,

E, on one side for attachment to the servicepipe.

On the upper part of the casting E is an npward-projecting .ring, 0, that tits within a recess, m, in the bottom of the valve-seat M. This valve'sea-t is provided with suitableports, m m, and its lower part is beveled internally to fit the corresponding upper portion of the valve N. 1

It willbe seen that by turning down the nut J the tube L will force the valve-seat M firmly against the upper part of the casting E, so that the ring 0 will enter the circular recess m and form a tightjoint. Suitablepackin g may be interposed, if desired.

At the lower part of the stand-pipe A is a waste-opening, n, that is governed by a valve, 0. This valve is provided with a stem, 0, that works in a box, which is attached to a rib ot' the valve-seat M, between two of its ports, at m. The valve-stem 0 is surrounded by a coiled spring, 0, the tension of which keeps the valve open until it is closed by the descent of the valve-rod H, when the beveled portion It of the latter comes in contact with the projecting end of the stem 0, and, forcing it outward,causes the valve 0 to close the opening a.

The valve N is opened and closed by turning the upper end of the screw-rod F, which works in the nut G, attached to the upper end of the valve-rod H, and by rotating the latter raises or lowers the valve N, so as to close or open the entrance through the valve-seat M.

P is the nozzle or outlet.

Q is a flange at the lower part of the standpipe A, and R is a flange at the upper part of the same. S is a similar flange at the lower part of the casting B. Openings for the passage of bolts are made through these flanges, as shown in Figs. 2 and 3, and also through the flanged plate D, by which the parts are united.

By this method of construction the entire working parts of the hydrant may be readily removed without disturbing the stand-pipe or breaking the pavement in which it is placed, thus greatly reducing the inconvenience and expense usually attendant upon the repairs of hydrants made in the ordinary manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a firehydrant, the combination, with the tube L, valve-seat M, and Waste-valve O, having stem 0 and coiled spring 0, of the valve N and rod H, having bevel h, arranged to close the wastevalve by coming in contact with the 10 stem 0, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
